AC Mounting bolt/header

[phlegm]

I have a strange one, wondering if anyone has delt with it. Ever since I went to a new set of headers, I cant get my AC compressor to line up on the bottom bolt. its off by a lot, like a half inch.

Anyone know if those nuts on there used to move? I am sure the one at the block is seized, but not certain about the one at the compressor side. I may try to pull it off and put it in a vice to see if I can get it to move, or go to the parts store and make one of my own with some red lock-tite and patience (of which I have neither... lol). Pic has it circled from LMC, but I cant find it in their calculator.

That’s a one piece stud - two sets of threads separated by the “nut”. Here’s a photo https://www.zip-corvette.com/64-76-3...cket-stud.html

Some people mistakenly think these are hard to come by but they really aren’t and the linked example is USA made.

Yeah, you may want to skip that bottom bracket if you're going with headers. There is an aftermarket bracket designed to mount the compressor. I've used one a couple of times, although I've nothing left with headers these days. May have been a Mr Gasket part but not sure. It's been a few years.

interesting, mine has the stud nut? but also a 2nd one, someone probably made it themselves like i was talking about doing. that explains the issue, my new headers are thicker at the block then my old ones were. I bet that extra space is causing the issue and the other nut wont go down any further or is seized. I may have to find a different bracket as suggested. Thanks guys.
